f 30% in a sample group of 200 French did NOT like tomatoes, how many in the group LIKED them?

If 30% did not like tomatoes, then the assumption is that 70% did like them.
70% of 200 French is .7 x 200 = 140, ans 140 tomatoe likers

Answer 2

Bob and his pals ate 35 % of his snack bag which had 140 nacho chips. How many nacho chips are left in the bag?

Answer 3

Pretty much same kind of problem. Use same kind of logic. If they ate 35% then that means (100-35) 65% remains in the bag. Since the bag held 140 chips
.65x140=91 chips remaining
